@dusx Good thinking Ryan, I'll try that.

Cheers,

I believe the edge blend is applied after the scenes are composited, and therefore can't be mixed in this way.

The only option I can think of is to ensure the same settings for edge blend for both scenes during the crossfade, and then animate the Edge blend values with envelopes after the scene change has occurred. If its possible, a cut rather than a crossfade would tighten it up, but other wise, flow one after the other ( I would need to test, but there is a good chance the values push through only once when the second scene is activated for cross-fade, so you may be able to start the edge blend animation a short while (0.25) after the initialization of the scene).

Good morning!

I'm using the Edge Blend Mask in 2 scenes, and my hope is that there would be a smooth cross fade between them. However, when the crossfade begins, the mask sort of flashes on and then it flashes off when the cross fade ends. Please see the video (watch the bottom of the screen).

It's the same mask in each scene and it looks great when we are just sitting in the scene. 

I don't want to use a Global Edge Blend, because I only need the mask for these two scenes. I've tried cropping with a softened edge, but it's not as good because I can't control the width of the softness like I can in the Edge Blend Mask actor.

Any thoughts would be welcome!

Thank you,

Hugh

You could adapt this template of mine and put an alpha mask inline: https://community.troikatronix.com/topic/5495/global-projection-mapping-simple-show-template

+1 on the Pipo sensors. John is an accomplished artist, technician, and veteran Isadora user so his recommendation of something is a glowing review. Ryan and I (both members of the Tech Team for Isadora) are testing them right now and really liking them. I’m testing with one or each Pipo sensor right now but I can already tell that I eventually want like 4-8 of each kind. Super easy to set up and very configurable.

I can't attend, wish I could, but it's really great seeing 'Isadora' events happening. We need more. Much love. 

Workshop: Live Cinema Creation with Retro-Digital Tools with Karla Kracht
November 6 to 9, 2025

Isadora Studio Berlin

A workshop for people curious about mixing digital and analog tools.
We will use live camera, projection and light with miniature sets, objects and drawings to create our own visual laboratory for live cinema. In a space of artistic experimentation, no prior experience is necessary, open to all interested in the possibilities of live cinema creation.

virtual stage in the background and then get stage image and put a mask on it from there

 This sounds like a smart way to extend your video pipeline. Or create a User Actor that is inserted before the projector in the scene and allows you to add an alpha channel. You could use listener broadcasters to insert any alpha you like from any other scene in that way.

@rwillats

another option is Pipo Interfaces (https://pipointerfaces.com/) the Pipo Analog is a device that you can use to connect 8 physical buttons that will send MIDI or OSC over WiFi into Isadora, so your switches could be distributed around the haunted house and all wired into the Pipo. Its not as cheap as Arduino, but I find its much easier to use.

@rwillats You could explore Arduino. A wireless Arduino board plus a light or pressure sensor could be used to trigger Isadora when change in a particular room is detected.

Isadora talks well with Arduino 😊
